The system includes more than one ozone generator (5, 18); more than one ozone level detector (6, 6 ', 7); a programmable timer (10); at least one occupancy detector (14); at least one major system process management tool (13); at least one intermediate system process management tool (11). The invention is intended to disinfect not only the air, the removal of bad odor, but also the disinfection of wastewater, premises and equipment by regulating ozone concentration. In this way, it is not only the result of bad odor that results from bacteria, protozoa, molds and other fungi, but also the reason for this bad smell, i. destroying viruses, bacteria, fungi, mold and all major biogas in a disinfected environment. The modifications of the present invention provide an opportunity to regulate ozone concentrations in order to disinfect wastewater, premises and the environment, avoiding the possible harmful effects of ozone on people working in disinfected environments or living in such environments.

Description

The present invention relates to a disinfection system and, more particularly, to a system and equipment for disinfecting sewage pumping stations and wastewater treatment plants (industrial and municipal).

State of the art

Modern society generates huge quantities of domestic and industrial wastewater. As the cities and settlements of the world grow and expand, the amount of domestic and industrial wastewater is constantly increasing. As a result, the problem of disinfecting sewage pumping stations and sewage treatment plants (industrial and private) and neutralizing bad odors is becoming increasingly acute. With the rapid development of global industry and public life, it is very common to hear (in print and television) that residents of cities and settlements constantly complain about the nasty smell of sewage pumping stations and sewage treatment plants. Citizens complain of worsening health, persistent headaches, nausea, increased depression and sudden mood swings. And this is fully understood and confirmed by research. Back in 2012, researchers at Vilnius Gediminas Technical University: Assoc. dr. Dainius Paliulis together with dr. Egle Zuokaite published a scientific paper Methodological Recommendations for Odor Management ”. The methodological recommendations have been prepared during the implementation of the 2007-2013 period. Implementation Measure VP1-4.3-VRM-02-V "Promotion of Public Policy Reforms" of the Operational Program for the Development of Human Resources Priority 4 "Strengthening Administrative Capacity and Increasing Efficiency of Public Administration"

All the problems that arise in society due to the disinfection of sewage pumping stations and sewage treatment plants and the unpleasant odors emitted are very clearly identified in this research. Also, in this scientific work it is very scientifically explained what causes all the above problems. It is true that the process of collecting, pumping and purifying wastewater results in extremely high levels of various microorganisms and methane, hydrogen sulfide, ammonia and other gases, and many other unwanted chemical elements.

Industrial and municipal wastewater accumulated in sewage pumping stations and wastewater treatment plants, or their contents, become a breeding ground for microorganisms (especially at higher temperatures), producing additional pollutants such as bacteria, protozoa, mold, etc., which in turn produce other organic pollutants. In addition, fungi, bacteria and gas not only accumulate in sewage pumping stations and sewage treatment plants, but are also airborne, particularly in places where residential or civilian buildings are located in the immediate vicinity of the sewage pumping stations and the worst situation is in urban areas near wastewater treatment plants, which are usually completely open. This poses a major risk to human and animal health. Very often, such sites can quickly infect vectors that spread bad odors (often even intolerable to human health).

Conventional methods of disinfecting and deodorizing the system of sewage pumping stations and sewage treatment plants (industrial and municipal) are either ineffective or ineffective. This is clearly evident from the above scientific work. Pages 45 and 46 of this work clearly illustrate the unsuccessful attempts to address the problem of bad odors at Vilniaus Vandenys, a company in the City of Vilnius, which in 2008 tried to install a smell-retention technology near the sewage discharge and composting sites, which are located near the Karoliniškės and Lazdynai neighborhoods in Vilnius. However, this is a very expensive and labor-intensive process and, as the wastewater flow is not reduced, the premises and sites of the wastewater pumping stations and wastewater treatment plants become very contaminated very quickly. In addition, water and chemicals used for disinfection do not always penetrate all cracks and cracks in the wastewater collection and recycling system, which can be a source of bad odors and contamination.

Automated systems for disinfection of sewage pumping stations and sewage treatment plants (industrial and municipal) are known, which neutralize and kill both surface and airborne molds, bacteria and other harmful microorganisms, as well as biogas. One such system is described in patent specification no. LT5977B (patent number 5977, filed December 27, 2013), also described in patent application no .: 017228 (application no: 2016110902, Russian Federation, dated 24.03.2016), which focuses on preventing the smell of sewage from reaching residential homes . According to patent application no. LT5977B (Patent Number 5977, Publication Date: 27.12.2013) and No: 017228 (Application No: 2016110902, Russian Federation, Date: 24.03.2016) attempt to address the issue only superficially, i.e. attempts are made to destroy the consequence of bad odors, but not the cause. Patent Application No. 017228 attempts to solve a problem by installing a methane sensor at a sewage pumping station and activating an ozone generator at the sewage pumping station when the methane concentration increases. Ozone gas is an effective disinfectant capable of effectively disinfecting large amounts of air to prevent the accumulation of biofilms, bacteria, fungi and biogas in a sewage pumping station. The use of an ozone generator in a wastewater pumping station is an effective way to eliminate bad odors and reduce the incidence of health conditions such as allergies, rashes, colds, viral diseases and legionellosis. It is also known that ozone inhibits the spread of mold and parasites and destroys most biogas. Thus, the system described in U.S. Pat. LT5977B and No: 017228 can greatly improve sanitation.

Nevertheless, the conventional wastewater odor control system described in U.S. Pat. The LT5977B has its drawbacks. In particular, it generates ozone only when an increased concentration of methane is recorded at the sewage pumping station. This system does not directly solve the problem of other pollutants present in the sewage pumping station itself. For example, there may be periods when the lower air temperature causes the sewage to ferment and rot more slowly. In these cases, the amount of methane released is reduced accordingly, making the system less efficient in dealing with residual biofilms, molds, other pests and biogas that may still be present in the sewage pumping station. In addition, while the system is an effective means of stopping the smell of sewage, it may be replaced by the smell of ozone gas, which is itself pungent and toxic. Ozone gas is also a harmful substance and high concentrations in a sewage pumping station can be unpleasant for people living close to it. Prolonged exposure to high levels of ozone can also lead to headaches, irritation of the eyes and respiratory tract and even more lasting adverse effects, including lung damage. No modifications are proposed in the system description to control the amount of ozone produced, which includes the use of ozone sensors to monitor the ozone level at the sewage pumping station and to shut down the ozone generator when the concentration is above a certain threshold. While such a simple protective shutdown mechanism can prevent dangerous high levels of ozone formation, other factors that may influence the determination of acceptable levels of ozone are not taken into account.

In view of this, the present invention seeks to solve some of the problems encountered with conventional systems for disinfecting sewage pumping stations and sewage treatment plants and for removing bad odors.

Brief Description of the Invention

According to a first aspect of the present invention there is provided a disinfection system for installation in a sewage pumping station comprising: an ozone generator for generating ozone for disinfecting air in the sewage pumping station and the wastewater itself; an ozone detector for measuring ozone concentration in sewage pumping stations; air flow detector; an intermediate control for collecting and transmitting data; and a central controller for controlling the ozone generator to generate ozone depending on the measured ozone concentration and the time of day.

According to a second aspect of the present invention there is provided a disinfection system for installation in wastewater treatment plants (open sewage treatment tanks), comprising ozone generators for directly generating ozone in the wastewater itself, which is mounted on the side of the open wastewater treatment tank intended for disinfection. wastewater from ozone-resistant pipes; an ozone detector for measuring ozone concentration in the environment, installed in a circumference around an open sewage tank; an intermediate controller for collecting and transmitting data and a central controller for controlling the ozone generator to generate ozone depending on the measured ozone concentration.

The purpose of the present invention is not only to disinfect the air inside and around sewage pumping stations and wastewater treatment plants, but also to directly disinfect the wastewater by blowing ozone. This would not only eliminate the effect of bad odor that occurs during fermentation and rotting, but also the cause of the bad odor, i.e. destroying viruses, bacteria, fungi, mold and all major biogas directly in the wastewater itself.

Modifications of the present invention provide the ability to regulate ozone concentrations in wastewater pumping stations and in the vicinity of wastewater treatment tanks to disinfect the premises and the environment and prevent potential adverse effects on workers in these environments and residents living near such facilities. In addition, the use of feedback systems ensures that the mandatory requirements for ozone concentrations set by the relevant regulatory authorities are not exceeded.

Fig. illustrates an ozone disinfection system for wastewater treatment plants (open sewage collection and treatment tanks) according to a second modification of the present invention.

Detailed Description of the Invention

According to a first aspect of the present invention, the disinfection system for installation in sewage pumping stations comprises: a vent; vent pipe or valve; at least three pairs of ozone generators for generating ozone for the disinfection of air at the sewage pumping station and of the wastewater itself; a first ozone detector for measuring ozone concentration in sewage pumping stations; and a second ozone detector for measuring the ozone concentration in the ventilation system openings at the sewage pumping stations; start relay; air flow detector; a timer; an intermediate controller; at least one other intermediate controller for collecting and transmitting data; a central controller for controlling the ozone generator, which generates ozone depending on the measured ozone concentration and the time of day; employment detector; deep drainage pipe; ozone-resistant plastic pipe; openings with non-return valves; check valves.

The system according to the first aspect of the present invention controls the amount of ozone in the air of wastewater pumping stations round the clock to achieve an optimal balance between efficient disinfection and a safe user environment. For example, disinfection is more effective at higher concentrations of ozone, but maintaining a high concentration of ozone during the day when stationary workers at the sewage pumping stations are at immediate risk of unpleasant or harmful ozone exposure. This can be avoided, for example, by maintaining a higher concentration at night or other times when workers are not working in the premises. This can increase the efficiency of ozone generation by combating microorganisms and pests at sewage pumping stations and at the same time ensuring that the relevant legal limit values are not exceeded. This means that during the day, when the sewage pumping stations are directly staffed, ozone concentrations may be allowed to fall to a lower level in order to avoid harmful effects on humans.

The time of day is set by a timer, based on which the central controller controls the ozone generator. This would be an easy way to control your 24 hour schedule, although there are other ways. For example, it is possible to install an outdoor light and / or temperature detector to separate day and night time.

Preferably, the central controller controls the ozone generators according to a programmed schedule and a set time of day. This would make it easy to plot the operating time of the ozone generator.

In addition, one or more of the following components may be taken into account when programming a schedule: time of year, days of work, and days off. In this way, the amount of ozone generated per day could vary depending on the time of year or pattern of employment. For example, at lower temperatures during the winter, the odor of sewage is less problematic than during the summer months.

It is desirable for the central controller to stop the ozone generator when the ozone detector detects that the ozone concentration exceeds the set stop value indoors. This would ensure that the modifications do not generate too much ozone. This possibility can be exploited, for example, to avoid exceeding the statutory limit values or the threshold above which humans are exposed to ozone.

It is desirable to have different concentration limits depending on the time of day. Then, during the day when high levels of ozone are expected, the limit values can be set based on the legal limit values, and during the day when low levels of ozone are expected, the limits can be set so that people are not exposed to ozone.

It is desirable that the ozone detector at the sewage pumping station be located away from the ozone generators so that the ozone is mixed with air prior to measuring the concentration. In this way, ozone concentration in sewage pumping stations would be measured more accurately.

Preferably, the disinfection system at the sewage pumping station would include an occupancy detector to detect the presence of persons at the sewage pumping station, where the central controller would stop the ozone generator upon detecting the presence of the person at the sewage pumping station. This would be an additional safeguard, as although ozone would still be present in the air at sewage pumping stations, it would no longer be actively generated and dispersed. This would allow the person to be safely indoors and avoid the long-term effects of high concentrations of ozone, which could be detrimental to their health.

It is desirable that the occupancy detector function is performed by at least one motion detector. In this way, persons in the room would be detected by their movement. Motion detectors of various technologies are available, such as infrared, microwave, ultrasound and tomography. Other types of occupancy detectors can also be used, such as door detectors that detect when doors are open at sewage pumping stations. In addition, combination sensors can be used in the occupancy detector to increase detection accuracy.

Preferably, the disinfection system further includes an airflow detector to measure the airflow from the sewage pumping station, where the airflow detector detects that the airflow has dropped below a threshold value, the central controller will stop the ozone generator. In this way it would be possible to quickly detect that the ventilation system of the system is blocked in the sewage pumping stations, thus preventing rapid accumulation of ozone gas.

It is desirable that the airflow detector should be fitted with brackets at the ventilation outlet of the sewage pumping station.

Preferably, at the sewage pumping station, the disinfection system further comprises a second ozone detector to measure the ozone concentration inside the ventilation outlet of the sewage pumping station, where the central controller would stop the ozone generator when the second ozone detector detects that it is above the second limit. This would be the second fuse to prevent excessive concentrations of ozone seeping through the ventilation outlet of sewage pumping stations in the building environment.

It is desirable to have different second limit values depending on the time of day. This would allow the system to operate more intensively at times of day when openings at sewage pumping stations are less likely to result in higher ozone concentrations.

Preferably, the second ozone detector should have brackets installed at the sewage pumping stations at the ventilation outlet.

It is desirable that at a sewage pumping station, the disinfection system additionally includes an intermediate controller from which data collected from the system elements is transmitted directly to the central controller. The central controller would provide remote monitoring and control of the disinfection system at the sewage pumping stations.

Preferably, the central controller includes an input for receiving response data from more than one intermediate controller from multiple sewage pumping stations. In this way, data from several sewage pumping stations could be monitored and compared.

Preferably, the response data is transmitted from the proxy controller to the central controller via cable, GSM module or internet connection.

According to a second aspect of the present invention there is provided a disinfection system for installation in sewage treatment plants (open sewage treatment tanks), which may, under certain conditions, cause mold and / or bacteria, and which may harm human health by airborne or unwanted / unpleasant odor.

The system includes ozone generators for generating ozone and supplying it directly to the wastewater itself, which is installed on the side of an open sewage treatment tank for disinfection, where ozone produced is routed directly to the wastewater by ozone-resistant pipes, ozone detectors for measuring ozone concentrations in the environment on the perimeter about an open sewage tank; an intermediate control for collecting and transmitting data; and a central controller for controlling the ozone generators to generate ozone as a function of the measured ozone concentration.

The present invention seeks to disinfect and eliminate bad odor and contamination not only in the air inside and around wastewater pumping stations and wastewater treatment plants, but also to disinfect and eliminate bad odor and contamination in the wastewater directly by blowing ozone. This would not only eliminate the effect of bad odor that occurs during fermentation and rotting, but also the cause of the bad odor, i.e. destroying viruses, bacteria, fungi, mold and all major biogas directly in the wastewater itself.

The system according to the second aspect of the present invention enables the control of ozone and the disinfection of wastewater, at dedicated sewage treatment plants (open sewage treatment tanks) and their ambient air 24 hours a day to achieve an optimal balance between efficient disinfection and a safe user environment.

It is desirable that the central controller stop the ozone generators when ozone is detected in the surrounding perimeter of the wastewater treatment tank to detect that the ozone concentration exceeds the set stop value. This would prevent systems from generating too much ozone. This possibility can be exploited, for example, in order not to exceed the legal limit values or the threshold above which users of the ozone depleting potential are exposed.

It is desirable to have different concentration limits depending on the time of day or year of the year. Then, during the day or year when high levels of ozone are expected, the limit values could be set based on the legal limit values, and during the day or year when the low levels of ozone are expected to be lowered people nearby.

It is desirable that ambient ozone detectors are located away from the place where ozone generators are installed so that ozone is mixed with air prior to concentration measurement. This would provide a more accurate measurement of the ozone concentration in the intended environment.

Preferably, the sewage disinfection system includes an intermediate controller from which data collected from the system elements is transmitted directly to the central controller. The central controller would provide remote monitoring of the sewage disinfection system.

Preferably, the central controller includes an input for receiving response data from more than one intermediate controller from multiple sewage collection and processing stations. In this way, several sewage collection and processing stations could be monitored and compared.

Preferably, the response data is transmitted from the proxy controller to the central controller via cable, GSM module or internet connection.

Examples:

example in fig. A schematic diagram of a disinfection system for sewage pumping stations according to a first modification of the present invention is provided. The disinfection system of this modification is installed in the room (3) of the sewage pumping station, which is connected to the vent (1). The vent (1) has a ventilation chimney at the top, which may be accessible to a person (3) or in the vicinity of human assembly spaces for disinfection of pumping stations, and which, under certain conditions, develop molds and / or bacteria which may harm human health, or resulting in an unwanted / unpleasant odor.

Preferably, the ozone generators (5, 18) are configured with respect to the size, ambient temperature, and humidity of the environment to be disinfected to enhance the efficiency of the ozone generated to combat the microorganisms present in that environment. In this regard, the effectiveness of ozone as a disinfectant depends on several factors, including the amount of ozone used, residual ozone in the medium and other environmental factors such as pH, temperature, relative humidity of the medium, organic matter content, etc.

The disinfection system according to the first embodiment comprises ozone generators (5, 18) which emit ozone to the disinfection room (3), to the sewage collection shaft (16) and directly to the waste water (17) and are controlled via a central controller (13). ). The ozone outlet of the ozone generator (5) is preferably adapted to direct a stream of ozone gas to and / or to disinfect the room (4). The ozone produced by the higher power ozone generator (18) is introduced through ozone-resistant tubes (19) which are connected to an ozone outlet head (20) which has ozone outlet holes (21) with a non-return valve (22). for ozone generators (18), the holes would not block the holes. The timer (10) is designed to control and control the time of day according to the schedule program and to send data to the central controller (13) via the intermediate controller (11, 12) to control the ozone generators (18) depending on the time of day. The timer for this modification includes a touch screen for entering control options and setting the timeline program.

In this modification, the central controller (13) is for receiving control information, via an intermediate controller (11, 12) via an Internet connection, from a timer (10), an ozone detector (6, 7) and a motion detector (14), and equipped with similar disinfection systems, intermediate controls (12). The central controller (13) is designed to monitor incoming control data and centrally regulates the settings by sending counter-instructions via an intermediate controller (11, 12) for controlling the ozone generators (5, 18).

The disinfected room (3) has an ozone detector (6) for measuring ozone concentration inside the room (3); a motion detector (14) for detecting the presence of persons in such a room (3) and a timer (10). All detectors (6, 7, 14) transmit the captured data to the central controller (13). This can be done through an internet connection. The ozone detector (6) is mounted separately from the ozone generator (5) and mounted on the wall of the room (3) away from the ozone generator, and preferably on the opposite wall of the room (3) in order to separate as much as possible. This is to allow the generated ozone to mix with the indoor air before reaching the ozone detector (6). The indoor ozone detector (6) thus measures the ozone concentration more accurately.

The motion detector (14) is mounted on the wall of the intended disinfection room (3) and configured. The sensor of the motion detector (14) is directed where only the movements of a person entering the disinfected room (3) can be recorded. Of course, other technical solutions can be used, such as a passive infrared detector designed to ignore smaller than human thermal footprints.

The air flow detector (9) is mounted at the top of the vent (1) at the junction with the vent and is used to measure the flow of exhaust air from the vent (1). In addition, an ozone detector (7) is installed to measure the ozone level at the outlet. Can be equipped with an air flow detector (9) to measure the ozone level of the outflow air. A control relay (8) is provided for transmitting the captured data to the intermediate controller (11, 12).

example in fig. A schematic diagram of a system for disinfecting sewage treatment plants (open sewage collection and treatment tanks) and of the wastewater disinfection system according to the second aspect of the present invention is provided. The disinfection system of this modification is installed in a disinfected environment i.e. wastewater collection or recycling tank and its environment in the vicinity of human meeting areas and where, under certain conditions, mold and / or viruses, bacteria and biogas may be present which may be harmful to human health or cause undesirable / unpleasant odors.

Preferably, the ozone generators (18) are configured with respect to the size of the environment to be disinfected, air temperature, and humidity to increase the efficiency of the ozone generated to combat the microorganisms in that environment. In this regard, the effectiveness of ozone as a disinfectant depends on several factors, including the amount of ozone used, the amount of ozone remaining in the medium and other environmental factors such as pH, temperature, organic matter content, etc.

The disinfection system according to a second embodiment comprises ozone generators (18), which emit ozone to a wastewater collection or recycling tank (3 ') for disinfection and are controlled via a central controller (13). The ozone produced by the ozone generator (18) is discharged directly into the wastewater (17) itself. Ozone is introduced through ozone-resistant pipes (19) connected to an ozone discharge head (23), which has ozone depleting holes (21) with a non-return valve (22), to prevent run-off of the holes when the ozone generator (18) stops operating .

In this modification, the central controller (13) is for receiving control information via an intermediate controller (11) via an Internet connection from the ozone detectors (6 ') mounted on the perimeter (3') of the sewage treatment tank. The central controller (13) is designed to monitor incoming control data and centrally regulates the settings by sending feedback instructions via the intermediate controller (11) to control the ozone generator (18).

Disinfected in the intended environment are ozone detectors (6 ') for measuring the concentration of ozone inside the environment and in the air in the protective perimeter. All detectors transmit the captured data to the central controller (13). This can be done through an internet connection. The ozone detectors (6 ') are located separately from the ozone generators (18) and are mounted on a perimeter guard away from the ozone generators so that the two devices are as separate as possible. This is to ensure that generated and unused ozone is used to disinfect wastewater, which, if burst into ambient air, mixes with ambient air before reaching the ozone detector (6 '). In this way, ozone detectors (6 ') in the environment measure the ozone concentration more accurately.

Each individual sewage disinfection system can function as a stand-alone system, but such a system cannot be error-prone and may cause false alarms due, for example, to mains failures, consumer errors, poor maintenance, over-voltage, lightning or equipment failures, so communication with the central controls (13) and (1) enables remote control of individual disinfection systems. This configuration allows for 24-hour monitoring of disinfection systems and rapid response to network failures, such as ozone concentrations above regulatory limits.

It is to be understood that the modifications shown above are merely exemplary embodiments of the invention. In practice, the invention can be applied to a variety of configurations where specific modifications can be readily prepared by one skilled in the art. To this end, for example, the disinfection system may be redesigned to include multiple ozone generators and / or ozone sensors, which may be installed or installed in different locations or environments to be disinfected, depending on the disinfected room and its environmental parameters. disinfection efficiency.
